Web1. Create or modify the testbench. Make sure your testbench has a timescale definition added to it. The following is an example timescale definition: 'timescale 1ns/100ps Refer to "Example Testbench" on page 8 for information about creating testbenches. 2. Create or modify the command file. A command file is only necessary if you are running batch WebLow simulation speed with VCS simulator. Hi , All : I am wondering if somebody encounters low simulation issue while migrating their designs from ISE10.1 to ISE12.4 . Recently I replaced my DDR2 Memory controller generated with MIG at ISE10.1 with new DDR2 Memory controller generated with MIG 3.6 at ISE12.4. However , I found out the …
